Pushing functions as closer to the edge of the network usually makes them easier to scale and more robust and resilient to failure. There might be more chance of failure, but there is less consequence.
Specific to CGN/LSN, I think the best idea is that if we can't have a 1 to 1 relationship between subscriber and global IPv4 address (in the ISP network that is), the next best thing is to try to keep as close to that as possible e.g. if you share a single IPv4 address between two customers, you've halved your IPv4 addressing requirements / doubled your growth opportunity, and allowed for e.g. 32K TCP or UDP ports for each of those customers.

But if you free up large swaths you might actually be generating additional revenue opportunity instead of only growth opportunity.
